"Rounded" buttons with SWT? [message #467179]

Is there a way to make or simulate buttons with rounded contours with
SWT? Something other than buttons with 90 degree corners? I'm looking
for something like that drawn by gc.drawRoundedRectangle().

Thanks

Eddie,

SWT uses the native system widgets to draw buttons. So for example, all
buttons are rounded on Mac OS X:
http://www.eclipse.org/vep/WebContent/docs/newAndNoteworthy/ 1.2-M1/swt-osx1.jpg

If you want your buttons to follow the Windows XP widget themes see this
FAQ item: http://www.eclipse.org/swt/faq.php#xpthemes

Otherwise, you can't really do much to affect the way the native widgets
are drawn. If you want different behavior, you'll have to create an
emulated button, rather than relying on SWT.

Hope this helps,
- Jeff

Maybe some custom widget project provides a button for you:

Yes. I guess I was partially wondering if there were any hints one
could provide or some other way to get SWT to round the buttons.

Thanks. I was aware of that, but this is for a Java Webstart
application where I don't believe we can do what is called for in that
FAQ item. Unless there is a way with SWT to have it follow the XP
widget themes even for a Webstart application?

Thanks for the help.

For you to have Windows XP themes over a Webstart, you will have to place the javaw.exe.manifest file in the jre/bin directory and rename it to javaws.exe.manifest. Then the application must be restarted. After the manifest has been placed, the XP theme will be followed. [Note:] Most of the time when the manifest hack doesn't work, it's because the manifest is placed in the wrong directory (i.e. not the one being used by the jre). This probably wouldn't be a problem if you use System.getProperties("jre.home") but I thought I'd mention it.

Oh, that's actually a lot easier than I was thinking. Thank you VERY
much! I'll try that out.

I tried this and it is just that easy. Totally awesome! Thanks again.
I haven't coded yet anything to copy the manifest into place, but with a
signed webstart application, one should have the privileges needed. And
maybe there's a trick one can play to get the manifest into place the
first time and then have the application re-run itself (or something) so
the application looks right the very first time it is run.

Someone ought to update the FAQ to specifically mention that this works
with Java WebStart.

FYI: I seemed to need to give a manifest to javaw.exe in the same
directory. It's possible that I didn't need to apply a manifest to
javaws.exe after all, since webstart seems to always run the application
itself with javaw.
